My descendant mitochondrial DNA is haplogroup K1A1B1A which is the most common group for Ashkenazi Jews.
In this case, however, my mitochondrial DNA was identified to belong to a subclade called K1A1B1A9 (with G1709A). So far only two other samples match K1A1B1A9 : identified as "JQ703069" and "JQ703485 " in a 2012 paper by Behar et. al
From other sources, I found these correlating samples as K1A1B1A9 - one from Berlin and one from Dlouhá Ves, Czech Republic :
Subgroup: K1a1b1a9 (with G1709A) https://www.yfull.com/mtree/K1a1b1a9/
Name: Not Disclosed Kit Number: 104763 Earliest Known Ancestor: N/A
Marker Location: N/A Lat, Lng: (52.3, 13.38) near Berlin, Germany
Subgroup: K1a1b1a9 (with G1709A) https://www.yfull.com/mtree/K1a1b1a9/
Name: Not Disclosed Kit Number: 95663 Earliest Known Ancestor: N/A
Marker Location: Dlouhá Ves, Czech Republic Lat, Lng: (49.57626, 15.6756716)
The estimated TMRCA (Time of Most Recent Common Ancestor) for the 3 samples is given as 350 YBP (Years Before Present) with a 95% confidence interval of between 75YBP and 1700YBP ... 3 samples is not enough to be accurate and that's why the range is so large).
